Longest-serving Representative to serve in the House: With more than 59 years of service, Representative John Dingell, Jr., of Michigan, holds the record for longest consecutive service.

Dingell has owned the title of Dean of the House of Representatives since 1995, given for the longest continuous service of a current member. The Michigan Democrat, born July 8, 1926, is not the oldest member of Congress. That honor goes to Rep. Ralph Hall, who is about three years older than Dingell.mail. Rep. John Dingell, who is serving his 30th term in the House of Representatives, is poised to break the record next week as the longest-serving member in the history of the U.S. Congress. Next Friday, June 7, Dingell will eclipse the late Sen. Robert Byrd, having served 57 years, 177 days.
